WINDOW FRAME AND SASHES.

To cllwnhom it may concern.-

Be it known that I, HARRY E. CAMPBELL, residing at ew York, in the county of New York and .Stete of New ork, have invented a certain new and useful Improvement in Window Frames and Sashes. of which the following a specification.

In U. S. Letters Patent No. 1,241,090, dated Sept. 25, 1917, and in other Letters Patent hitherto granted to me, I have set forth a WIlIldOW frame and sash construction wherein the hollow jambs and the sash frames are all of sheet metal, and wherein the sliding. sashes have laterally extending f plates on their vertical members entering slots in the inner walls of the jambs.

This construction having entered into very extensive use, I have been led to study the roblem of constructing wooden sashes and ambs with the object not only of securing to this type of structure certain advantages incident to the wholly metal construction,

but the overcoming of difiiculties which are peculier' to the wooden construction; and, in addition, of producing a simple structure easily and'cheeply made by the house'carpenter or builder.

In the accompanying drawings Figurel is a horizontal section through the ends of thesashes. end one of the hollow jambs. F ig. 2 is at similar section, with portioiis of the jambwalls broken away. In

Fig. 1 the laterally extending plates Q, R are shown secured to the front sides of the s eshe's, and in Fig. 2 said plates are shown secured to the rear sides. Fig. 3 is a section similar to Fig. 1, showing the wooden members incased in thin sheet metal for fire protection purposes, suchprotected wood bemg commonly known in the market as kala- Fig.4; is a. vertical section on the f.iFig- ;-$1 Q s Po s t s elfi t 9 h w por n 9 t 1 1 g 's-Qt e i ets t sw r m r l n 4,,

a manner of making the edged the plate at justable with respect to the fees of b I.

Similar letters of reference indicate like parts. I

A and B are sliding sashes, provided 'with any suitable counterbalancing means, not shown. The sash frames are of wood, and the glass panes C are seated in said frames and secured by strips D in any suitable way. The two jambs respectively on opposite sides of the sashes are alike, so that a description of one jmnb applies to both. Said jambs are hollow, and theirwalls eve of wood. One of the jambs is shown at E, and comprises the 'followin parts: a rear wall F, and outer side wall ,a front wall H, and an inner side well formed eshereinafter described. The outer side Wall G is secnred to the rear wall F and to the front wall H. Seated at one edge in a mortisein rear'wall F is a. wooden bar I which roje'cts into the space within the jamb an 'is parallel to well G. Secured to the face of'ber I is a transverse partition J, with the face of which the edge of the side rail of sash B is in sliding contact. The inner amb well has an outer member K seen to front wall H, and an inner member L secured to rear, Wall F and preferablkmeeting bar 1. The free edge of member is-beveled and preferably rounded, as shown at 'M. .011 the inner member L is a; projection, similerly beveled and rounded, as shown at N. The partition J is flared at its free edge and beveled as shown at() and P. y

The plate Q is attached to'sash B, passes through the slot between edges M 0, and at its free end is preferabl .ni sliding contact with the, face of bar ,"Ifhe plate It is attached to sash A, passes through the slot between edges N, P, and at its free end is refer-ably in sliding contact also with the ace of bar I. In'Fig. 1.. the slates Q, R are secured to the front side,'.an in Fig. 2'tothe rear side of therespective sashes. Either arrangement may be adopted,- the-maker may desire. In Fig. 3 the 'arranaaglcn i of plates shown hc'wooden'memr hers s own in -8 are each covered with thin sheet metal or purposes of fire protcction. Such'coverif' 18 no part of my present invention, my: objectbeing simply frames and iaifili are ofwood, the laterall extending ates Q,- B only being of meta As thesep this are sim ly flat'strips, preferably equaling in lengt the sashside rails to which theyaie allixed, they can easily be attached by screws, for example, as shown at S, by-any ca enter.- Said plates ar aof course" on both 5 de's of each sash.

Eachp'late' is a; barrier to the entrance of moisture or die e k of air through the joint between sash and frame.- The partition J .is still another barrier. It is practically impossible for either moisture or aircurrents to pass over the front side of plate Q, through the joinfthetween the edge of that plate bar then along the rear side :of saidplateyand e'joint between the-sash and g ct onflisndthw rav around the pla in the mefway,"-n d still getinto the building/ cadences" es "andirames are, as veeli blown; dilficult to kee weather. :ti' t .ee egther eeti, a cu te... on e ient is the-applicat on of ma er- In construction no weatherstrips' are at all.
